The National Hockey League (NHL; French: Ligue nationale de hockey—LNH) is a professional ice hockey league in North America, currently comprising 31 teams: 24 in the United States and 7 in Canada. The NHL is considered to be the premier professional ice hockey league in the world, and one of the major professional sports leagues in the United States and Canada. The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league playoff champion at the end of each season.
The National Hockey League was organized on November 26, 1917, at the Windsor Hotel in Montreal after the suspension of operations of its predecessor organization, the National Hockey Association (NHA), which had been founded in 1909 in Renfrew, Ontario. The NHL immediately took the NHA's place as one of the leagues that contested for the Stanley Cup in an annual interleague competition before a series of league mergers and folds left the NHL as the only league left competing for the Stanley Cup in 1926.
At its inception, the NHL had four teams—all in Canada, thus the adjective "National" in the league's name. The league expanded to the United States in 1924, when the Boston Bruins joined, and has since consisted of American and Canadian teams. From 1942 to 1967, the league had only six teams, collectively (if not contemporaneously) nicknamed the "Original Six". The NHL added six new teams to double its size at the 1967 NHL expansion. The league then increased to 18 teams in 1974 and 21 teams in 1979. In the 1990s, the NHL further expanded to 30 teams, and added its 31st team in 2017.
The league's headquarters have been in New York City since 1989 when the head office moved there from Montreal.
After a labour-management dispute that led to the cancellation of the entire 2004–05 season, the league resumed play in 2005–06 under a new collective agreement that included a salary cap. In 2009, the NHL enjoyed record highs in terms of sponsorships, attendance, and television audiences.
The International Ice Hockey Federation (IIHF) considers the Stanley Cup to be one of the "most important championships available to the sport". The NHL draws many highly skilled players from all over the world and currently has players from approximately 20 countries. Canadians have historically constituted the majority of the players in the league, with an increasing percentage of American and European players in recent seasons.
The NHL Entry Draft (French: Repêchage d'entrée dans la LNH) is an annual meeting in which every franchise of the National Hockey League (NHL) systematically select the rights to available ice hockey players who meet draft eligibility requirements (North American players 18–20 years old and European/international players 18–21 years old; all others enter league as unrestricted free agents). The NHL Entry Draft is held once every year, generally within two to three months after the conclusion of the previous season. During the draft, teams take turns selecting amateur players from junior or collegiate leagues and professional players from European leagues.
The first draft was held in 1963, and has been held every year since. The NHL Entry Draft was known as the NHL Amateur Draft until 1979. The entry draft has only been a public event since 1980, and a televised event since 1984. Up to 1994, the order was solely determined by the standings at the end of the regular season. In 1995, the NHL Draft Lottery was introduced where only teams who had missed the playoffs could participate. The one lottery winner would move up the draft order a maximum of four places, meaning only the top five-placed teams could pick first in the draft, and no team in the non-playoff group could move down more than one place. The chances of winning the lottery were weighted towards the teams at the bottom of the regular season standings. Beginning in 2013, the limit of moving up a maximum of four places in the draft order was eliminated, so the lottery winner would automatically receive the first overall pick, and any teams above it in the draft order would still move down one spot.
